Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The primary purpose of this study is to assess whether Acelarin (NUC-1031) is superior to gemcitabine in terms of overall survival for treatment of patients with metastatic pancreatic carcinoma. In addition disease progression, quality of life and comparative safety will be evaluated. Secondary objectives are to compare between the two treatment groups the following:
* Progression Free Survival (PFS)
* Radiological Response and disease control rate
* Toxicity and safety
* Quality of Life
Additional, exploratory objectives are to discover and validate possible biomarkers to predict additional benefit of Acelarin (NUC-1031) over gemcitabine alone.
* Progression Free Survival (PFS)

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Pancreatic cancer remains the most lethal of solid tumours with little progress being made to improve patient outcomes over the past 30 years of research. The incidence in the UK is approximately 9,000 new cases per year and, with a 5 year survival remaining at just 3%, mortality approximates incidence. These dismal outcomes reflect:
1. Advanced stage at presentation such that only a minority of patients are suitable for surgery with curative intent;
2. High rates of recurrence even in those undergoing radical surgery;
3. Limited efficacy of systemic therapies.
Until recently, the mainstay of systemic therapy for advanced pancreatic cancer was gemcitabine, based on the pivotal study in 1997 by Burris et al., reporting a survival and clinical benefit when compared with 5-FU. However, this benefit is modest with median and 1-year survival of approximately 6 months and 20% respectively for patients with metastatic disease. Combination chemotherapy has shown more promising results but at the expense of significant toxicity limiting this to younger patients with good performance status.
Although these chemotherapy combinations confer a survival advantage over gemcitabine, their use is restricted to a cohort of patients able, and willing, to tolerate additional toxicity. Pancreatic cancer is commonly associated with:
(i) increasing age; (ii) co-morbidities (for example, diabetes mellitus which, if associated with peripheral neuropathy, may limit the safe administration of neurotoxic drugs such as oxaliplatin and nab-paclitaxel); (iii) symptoms that negatively impact on performance status; (iv) biliary obstruction requiring stenting, with associated risks of sepsis and impaired drug metabolism.
Thus, for a large proportion of patients single agent gemcitabine remains an appropriate standard chemotherapy. For this group of patients, more efficacious and better tolerated treatment is required.
The study is being performed to investigate whether Acelarin provides improvement in overall survival compared with gemcitabine. This is a pivotal study in this indication and will represent the landmark data for whether there is additional benefit from Acelarin in pancreatic cancer.
Gemcitabine monotherapy, the control arm, remains a standard of care in this disease. The only treatments that have shown improved outcome over gemcitabine are Folfirinox and nab-paclitaxel in combination with gemcitabine. However, the application of these regimens to a large proportion of patients with pancreatic cancer is limited by the potential for significant toxicities.
Acelarin (NUC-1031) is a first-in-class nucleotide analogue, which uses novel phosphoramidate technology to overcome the key cancer resistance mechanisms associated with gemcitabine.
Acelarin is synthesised as a pre-activated molecule bearing one protected phosphate group, termed the phosphoramidate motif, imparting several potential advantages to this new agent over gemcitabine:
* Acelarin (NUC-1031) overcomes the reliance on nucleoside transporters to cross the cellular membrane for effective uptake by the cancer cells.
* Acelarin (NUC-1031) presents the cell with an already partially activated (monophosphate) form of the nucleoside, thereby obviating the need for the rate limiting initial kinase activation.
* Acelarin (NUC-1031) is protected from enzymatic breakdown (especially by deaminases and phosphorylases) resulting in greater stability and a reduction in the generation of toxic metabolites.
The clinical relevance of these resistance mechanisms has been well documented.
Multiple active nucleoside transporters located in the cell membrane carry out the transport of nucleoside analogues, such as gemcitabine, into the cells. The human equilibrative nucleoside transporter, hENT1 mediates the majority of gemcitabine uptake. It is therefore expected that hENT1-deficient cells are highly resistant to gemcitabine (Achiwa et al., Cancer Sci. 2004).
Nucleoside transport deficiency is an important predictive factor for gemcitabine response in patients with cancer. Spratlin et al.,demonstrated that the presence of nucleoside transporters correlated with improved response to gemcitabine and OS in patients with pancreatic cancer (Spratlin et al Clin Cancer Res. 2004). Patients expressing hENT1 had a median survival of 13 months compared to only 4 months in patients with little or no hENT1 activity.
Acelarin has been shown to overcome the need for hENT1 active transport to enter the cancer cells. The greater lipophilicity allows Acelarin to cross the cell membrane independently of nucleoside transporters.
To become active, nucleoside analogues require sequential steps of phosphorylation within the cancer cells. Deficiency in dCK is a frequently described form of in-vitro and in-vivo inherent as well as acquired resistance to gemcitabine. Acelarin is synthesised as a monophosphate agent and, as such, has by-passed the rate limiting step of kinase-dependent activation.
Acelarin bears a phosphoramidate moiety on the ribose 5' carbon, which protects the compound from deamination (Slusarczyk et al J Med Chem 2014) , which may confer considerable survival advantages and a more favourable safety profile (Ghazali et al JCO 322:5s, 2014).
It is planned to perform this study in approximately 40 UK centres with additional centres in Europe and the USA with a centre defined as the primary institution of the clinical investigator. Recruitment will be competitive and 328 patients will be randomised in a 1:1 fashion.
Randomisation will be stratified by ECOG performance status (PS) (0/1 vs 2).
Baseline radiographic assessment of disease will be performed within 28 days prior to first treatment and first treatment will be delivered within 8 days of randomisation or the earliest screening procedure, e.g. blood samples, CT scan whichever is sooner as follows:
Arm A (experimental arm): Acelarin (NUC-1031)
Acelarin: 825 mg/m2 administered intravenously over 15 to 30 minutes on days 1, 8 and 15 of a 28 day cycle
Arm B (standard therapeutic arm): Gemcitabine
Gemcitabine: 1000mg/m2 administered intravenously as a 30 minute infusion on days 1, 8 and 15 of a 28 day cycle
Patients will be seen on a weekly basis during the time they are on active treatment and will be treated until disease progression. At the completion of therapy, an end-of therapy visit must be completed within 7 days after the decision is made to discontinue all therapy. This must be a full assessment consisting of physical exam, Performance Status, ECG, haematology and chemistry profile and toxicity/AE assessments, after which follow up will then occur every 12 weeks. CT scans of the chest, abdomen and pelvis will take place at screening then every 12 weeks thereafter until disease progression as per RECIST 1.1.
No further anti-tumour treatment will be initiated until progression of disease. AE information will be collected until at least 30 days after the last dose of study therapy is administered or until all study therapy-related AEs have resolved, stabilised or been deemed irreversible and a 30 day safety follow up should be performed at this point.
A phase I/II clinical study has established the RP2D and schedule for Acelarin as 825 mg/m2 administered intravenously on days 1, 8 and 15 of a 28 day cycle. Two dose limiting toxicities were observed (grade 3 transaminitis at 725mg/m2 and grade 4 thrombocytopenia at 750mg/m2). Otherwise treatment was well-tolerated with no unexpected adverse events. Adverse events were generally mild to moderate with the most common grade 1 and 2 AEs being anaemia, fatigue, transaminitis and thrombocytopenia. Only three patients experienced grade 4 AEs: thrombocytopenia, hypomagnesaemia and sepsis.
The following precautionary measures will also be put in place:
* Assessment of full blood count, renal function and liver function will be made prior to each administration of Acelarin.
* The occurrence of haematological toxicity including neutropenia and thrombocytopenia which requires dose adjustment is specified in the protocol.
* The effect of renal impairment on exposure to Acelarin in patients with renal impairment is not known. Therefore study entry is restricted to patients with creatinine clearance ≥ 30mL/minute.
* Acelarin should not be administered to pregnant women. A negative pregnancy test should be confirmed before administration of Acelarin for all women of childbearing age.
* There is no known antidote for Acelarin, and treatment of AEs associated with its use should be for the underlying adverse symptoms.
* Since Acelarin will be reconstituted in specialist oncology pharmacies and administered by experienced chemotherapy-trained nurses via intravenous injection, overdose is considered to be highly unlikely. There is no specific treatment for an overdose of Acelarin. In case of overdose, therapy may be interrupted, and any adverse reactions treated symptomatically.
